Application filed March 1, 1915. Serial No. 11,387.

To all whom it may concern:

Be it known that l. l-lnnnnn'r CHAMPION l'lAIHilSON, a subject of the King of Great Britain. residing at Loekport, in the county of Xiagara and State of New York, United States of America, hare inrented certain new'nnd useful lmproroments in Processes of Making Antimobile-Radiator Sections; and 1 do hereby declare the following'to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a method of making radiator units for automobiles and has for its object to improve the methods heretofore proposed, as well as to produce a -better radiator unit for the same cost than has been possible with the prior methods.

With these and other objects in view the invention consists in the novel steps constituting the process and in the novel construction"of part-s constituting the article all as will be m0r e fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the views-Figure 1 is a diagrammatic edge view of a radiator strip employed for the outer Walls of the radiator unit; Fig. 2 is a View similar to Fig. 1 but showing one end of the strip folded upon itself to partially form the two sides of the radiator unit; Fig. 3 is a view similar to Fig. 2, but showing the strip treated or bent in about its middle portion toenable it to be folded back upon itself toform the outside walls of the radiator unit; Fig. 4 is a diagrammatic riew illustrating the strip shown in Fig. 3 folded back upon itself to form the outer walls of the radiator unit and prorided between said walls with a separating or dirision plate; Fig. 5 is an enlarged edge view of the outer-walls ofthe radiator unit shown in Fig. 4 with the dirision plate omitted and illustrating the construction of the edges of said outer wall-Ii; ig. 6 Se-H enlarged edge \lQW of a portion of the'di-.

vision plate shown in Fig. 1; Fig. 7 is an enlarged sectional view of a portion of the parts shown in Fig. 4 contacting with one of the walls of an adjacent unit, to form a water passage between the units; Fig. 8 shows a diagrammatic end View of a plurality of units contacting with each other and illustrating the construction of the edges of the outer plates of each unit and also the water passages between the units; and Fig. 9 is a diagrammatic elevational.

view partly in section of a complete radiator made in accordance with this invention.

Referring to the drawing 1 indicates a strip of thin sheet metal which is substantially twice as long as the finished radiator unit, and said strip is repeatedly folded upon itself as indicated at 2 to form internal division walls between the cells, and it is repeatedly bent at an angle to itself between said division walls as indicated at 3 to form the outer thin walls of the radiator unit as will more clearly appear below. The operation of imparting to the strip 1 the walls 2 and 3 is well known in this art, and need not be further disclosed. After the long strip 1 is thus corrugated or produced, one of the bent walls 3, preferably the third or fourth wall 3 from the extreme end of the strip, is flattened out so as to eliminate the angular or bent portion 4, and to prov de the straight portion 5 shown in Figs. 3, 4 and 5. The said portion 5 is next bent flat down upon the adjacent folded portions 2 as indicated at 6, so as to formvthe integral end to the radiator unit which is best illustrated in Fig. 5. In order to better form this said integral end the strip 1 is further sharply bent at the adjacent wall 3 as indicated at 7 in the drawings and thereby permit the folded over end portion 8 to lie parallel with the longer body portion 9 as indicated in Figs. 2 and 5. The next step in the formation of the radiator section is to further flatten out one of the walls 3 located at such a point in the length of the strip 1 as will permit the parts to be folded over upon each other and to complete the outer walls of the unit as will presently appear. v

The second point selected for flattening out the walls 3 is indicated at 10 in Fig. 3, and the flattened wall 3 is there indicated by the numeral 15 and said member 15 is llattened down upon the. adjacent folded members 2 as will be clear from the drawings. The next step in the forming of the radiator unit is the bending of an adjacent wall 3 sharply upon itself asindicated at 11 so as to permit the member 12 of the strip -1 to be folded back upon the member 13 of said strip to form the outer walls of the unit as indicated in Fig. 4. Before this folding action occurs however a separating or division plate 16 is inserted between the walls 12 and 13 as also indicated in Fig. 4

whereupon the eXtrei-ne end 17 of the memher or wall 12 is inserted in the loop 18 of the bent over end S, as is clearly disclosed in Figs. 4 and Thesaid members 17 and 20 18 may he permanently secured together by g a drop of solder or by a soldering step itself later to be disclosed.

The division plate 16 which is inserted between the outer walls 12 and 1,3 of the radiator unit is best shown in Figs. 6 and 7,

and it consists of a body portion 20 from which is-struck out or punched out on one side thereof the guide flanges or strips 21 and on the other side thereof simila guide flanges or strips 22. These said strips 21 and 22 are each provided with the angular or bent portion 21,- and said angula'i portions 24, as uell as the. guide members 21 and 22 are so located that they are in stag- 'gered relation to each other as will be clear from the drawings. In, other words it will he clear that each strip 21 and 22 is thus provided with a pair of inclined surfaces 25 againstwvliich the edges of the folded over 40 internal wall members 2 strike and areguided to the points 26 on the main body plate 20 from which each pair of surfaces 25 were struck. It therefore follows that if before the extreme end members 17 and 18 of the wall 12 are secured together, the wall 13 is laid fiat with its members 3 resting upon a support and the division plate 16 is laid in on top of the inner folded walls 2 o'f said'outcr wall 13, that the guide members 25 of the said division plate 16 will cause the said plate 16 to be guided relatively to the folded members 2 into the proper position so that the edge of each folded member 2 will automatically so to speak, find its own point 26 and will therefore in a sense center itself. Further if now the other outer wall 1210f the'radiator unit is folded back upon the said division plate 16 its inner folded members 2 will likewise automatically find their points 26 and therefore automatically center themselves. It results from this that the problem of properly centering the parts-while assembling the same isvgreatly lessened. Further since the diover an end suchas 8 shown in Fig. 2 to vision plate 16 is provided with guide memhers 21 and 22 on each side thereof and staggered in relation to each other, the folded members '2 of the one wall 13 are staggered in relation to the folded members 2 of the other wall 12, 'so that there is a wider s ace between the walls 12 and 13 than t are would be if only one set of members 21 or 22 were employed and the folded members 2 of the respective walls Hand 13 came oppo' site each other or contacted on opposite sides of the same points 26. By constructingthe division plate 16 as described, the radiator units can he madeof a wider cross section and therefore they can accommodate more cooling air or fluid than would otherwise be the case. In addition to the above the stag-- gered relation of the members 21 and 22 more effectually breaks up the air as it passes through the radiator units than would be the case if only one set of members 21 or 35 22 were provided! After a radiator unit is constructed Las just disclosed, the parts are held in the sition indicated in Fig. 4, whereupon an other similarly constructed radiator unit is brought up to it so that the outer edges-0f each unit will contact as illustrated in- Fig.

8. Thatis to Ma the edges of the strips 1 are offset aseindicated at 30 in Figs. 5, 7 and S, and when two units such ,as 31 and 32 5 are brought together as indicated in Fig 8, the offset walls 30 of each unit contact with each other to leave a space running at right angles to the cells illustrated in Figs. 4 and 7, and which space 33 constitutesii water passage. The construction will be clear from Fig. 7' wherein the wall 35 of a unit such as 32 is shown in contact with the wall 36 of a unit such as 31, and wherein the oii'set edges 30 of the contacting units meet along the zig 'zag line 37 to form a zig zag water passage 33 running at right angles to the air cells. A pluralityof units may he thus suitably assembled, the parts secured or clamped together in any desired manner, when the edges embracing the offset members 30 are dipped in a bath of solder whereupon the parts are firmly secured together. A suitable number of units 31 and 32 will constitute a radiator section 40, and a suit able'number of radiator sections 42 may be assembled into any suitable casing such as 41 and the radiato'notherwise completed.

It will thus be seen that by first bending leave the folded pocket 18 for the reception of the extreme end 17 of the s'tri 1, and by bending out or flattening Otltnthfi wall members 3 in the strip 1 to form the integral end ortions 5 and 15 of the unit. I am enabled 0 do away with the necessity of putting in individual strips and soldering them in place in order to secure the outer walls 12 fist :nnl i h :n; exweilingly strong th in ilzziithe vxtrmnv hent nwnr the Mi l 9 lit up ;i; *:i in.-- t tho in i lo of 1h Emit. nu :0." tl of ihv watt-time nd mrm n wr oi wingh for tho reception of :aohior 311%. tlinirvl it Elm, strong i ifi i tight; Will l-r vim-maul hi art, that 0 radiators plvtul inmt ho twi l sinuihv sohlvring (loans. hv the dipping Plfliir-k It, i ely ilil I'tili ini'lved to Pl'fVQXli; 10m in i-i r fr more plaichid the expense of lllitll 'tp' thv-o h-zihs aim urhloring them up o hnnzl b ttt with grr-at 'lhemlore the lit'illltflf rid rt thrhpcvnil joint? which have m-n liervtot'osv r vi my ai ihv Point? and it ll ll sulmltming only th joint all forttul lay h-u futltS ET and. 1S hu a very tlvcideil ".iYllJlIi in the coiirt tmtion of rmliziioi' HiCiifillf I will further iw {LPPFPPlRlT-d by those skilled in the art; that the mw iision of :1 (liY'hion pinto lllCll as '16 which is not only self centviing but which affords the Wide Separation oi the outer walls 12 and i3 of well radiator unit is a decided. advantage, \Yhilr it does not zuhl materially to the total weight vf tlw radiator unit-l As a matter of fin-t all of i'm parts are made of very thin slirvt invtiil and it radiator made in accord- :nnw with thr Allow (lisrlosnn; is; comparw tin-l wry light and uxvwtlingly fitrong.
